In an eDP application, HPD is not required and on most bridge chips
useless. If HPD is not used, we need to set initial status as connected,
otherwise the connector created by the drm_bridge_connector API remains

There are some `static const u8` variables that are not used, this

drm_encoder is maintained in the mtk-dpi driver but the end goal is move all the
dummy drm_encoder (mtk-dsi, mtk-dpi, etc) to the main mtk_drm_drv driver.

This is really a cosmetic change just to make a bit more readable the
code after convert the driver to drm_bridge. The bridge variable name
will be used by the encoder drm_bridge, and the chained bridge will be
named next_bridge.

The mtk_dpi driver uses an empty implementation for its encoder. Replace
the code with the generic simple encoder.

he mediatek dsi driver in
mainline, so should be safe to switch to the new chain of drm_bridge API
unconditionally.
The patches has been tested on a Acer Chromebook R13 (Elm) running a
Chrome OS userspace and checking that the valid EDID mode reported by
the bridge is selected.

The PS8640 DSI-to-eDP bridge can retrieve the EDID, so implement the
.get_edid callback and set the flag to indicate the core to use it.

Replace the manual panel handling code by a drm_panel_bridge. This
simplifies the driver and allows all components in the display pipeline
to be treated as bridges, paving the way to generic connector handling.

In an eDP application, HPD is not required and on most bridge chips
useless. If HPD is not used, we need to set initial status as connected,
otherwise the connector created by the drm_bridge_connector API remains
in an unknown state.

Definitively we shouldn't select the MTK_MMSYS and we should depend on MTK_MMSYS
instead, so
